We are pleased to announce the release of WikiTrust version 2.
With it, you can compute author reputation and text trust of your wikis in real-time, as edits to the wiki are made, and you can display text trust via a new "trust" tab. The tool can be installed as a MediaWiki extension, and is released open-source, under the BSD license; the project page is http://trust.cse.ucsc.edu/WikiTrust A demo of the project (using an older, batch version of the code) on the 2007 English Wikipedia is available at http://wiki-trust.cse.ucsc.edu/
WikiTrust can be deployed both on new, and on existing, wikis. WikiTrust stores author reputation and text trust in additional database tables. If deployed on an existing wiki, WikiTrust first computes the reputation and trust information for the current wiki content, and then processes new edits as they are made. The computation is scalable, parallel, and fault-tolerant, in the sense that WikiTrust adaptively fills in missing trust or reputation information.
On my MacBook, running Ubuntu under vmware, WikiTrust can analize some 10-20 revisions / second of a wiki; so with a little patience, unless your wiki is truly huge, you can just deploy it and wait a bit (the computation happens in the background, of course, so you don't need to close access to the wiki to perform it).
Feedback, comments, etc are much appreciated! And of course, let us know if you have questions!
